Yes, it is necessary to use an adhesive when installing TIER™ on vertical surfaces. We recommend TIER™ glue, which is specifically engineered and cut for this. Use premium flexible polyurethane adhesives. Additionally, primers can be used to supplement the bond between the adhesive and the wall. Test the quality of the bond between the TIER™ board, the selected adhesive and the vertical surface ahead of the actual installation. Use an adhesive with adequate working time (minimum of three hours).

An expansion gap of at least a 5 to 10 mm is required. Use spacers around the perimeter of the flooring area during installation. Remove spacers before trim is installed. Ensure the expansion gap is clean of all debris before installing trim and that the trim rests upon the TIER™ boards to prevent debris collecting in the expansion gaps.

Remember to also leave expansion gaps whenever the floorboards meet an obstruction, such as pipes, columns, fireplaces, door jams, and even unusually heavy loads. Undercut door jams to create a seamless finish between the frame and the boards, whilst maintaining an expansion gap below the frame.

TIER™ floorboards are suitable for Grade 1 (SANS 10155) floors; permissible deviations should not exceed 3 mm at any point in a 3 m line. If the tile installation conditions comply with these conditions, TIER™ can be installed directly onto the tiles.

Small imperfections in some surfaces can be corrected with a belt sander. Large imperfections can be corrected with a standard or self-levelling screed.

TIER™ flooring is scratch resistant and will not scratch under normal use and with basic upkeep, such as sweeping or vacuuming loose debris. However, we recommend using felt pads beneath furniture. If you plan to move heavy furniture, lift the furniture when moving it.

Sweep or vacuum loose debris regularly to prevent sharp particles from being trodden into the surface. For stubborn dirt, mop your TIER™ floor using a low concentration mixture of water and dishwashing liquid. After mopping the surface, remove all excess water. We advise against using polishes and waxes.

Robotic vacuum cleaners and robotic mops can be used on TIER™ flooring. However, do not use industrial floor cleaning equipment which employs an aggressive brush or similar process, as it may damage the TIER™ flooring wear layer.

TIER™ flooring can be installed over areas of up to 400 m2, or in consecutive lengths of up to 30 m, without the need for threshold trim. Use appropriate threshold trim profiles for areas or lengths greater than this. We can recommend local suppliers of trim for your convenience.

We do not supply matching accessories for TIER™ flooring. The technology and materials used to create TIER™ floorboards are different from that used to create flooring accessories. Therefore, it is extremely difficult to perfectly match the finishes of accessories to floorboards. This is a common issue with all flooring systems.

We suggest using simple, plain-coloured accessories for an elegant end look. We recommend using quality, foamed PVC and/or aluminium accessories so that the benefits provided by TIER™ flooring, such as water resistance, biodegradation resistance, etc., are provided by the entire floor system. We are happy to recommend local suppliers for these products.

TIER™ flooring can be installed in areas that are exposed to sunlight or UV rays. TIER™ floorboards offer a UV-resistant wear layer to prevent the colours of the film layer from fading significantly.

Do not install TIER™ flooring in areas that are constantly wet.
Although TIER™ flooring is highly resistant to water absorption, it is not impervious to water. “Water resistant” is frequently confused with “waterproof” in the flooring industry, and even products such as ceramic or porcelain tiles (with their necessary grout) are not fully waterproof.

The joints between TIER™ floorboards are designed to be watertight. However, water may seep through these points when subjected to large volumes of water for extended periods of time. Water may also seep around skirting, trim or reveals. Although the TIER™ floorboards, themselves, will not be damaged, water below the floorboards can result in uneven distribution of loads and may damage joint profiles between boards. The foamed IXPE underlay of TIER™ flooring is coated using an antimicrobial additive to inhibit the growth of a wide range of microorganisms. However, extended exposure to stagnant water increases the susceptibility of microbial growth in joists and accessories, particularly in warm environments such as bathrooms or kitchens.

If water does seep below your TIER™ flooring, remove the boards, allow the subfloor and the floorboards to dry completely (for allowable limits, refer to Annexure B in SANS 10070) and then re-install. Do not leave water below the floorboards. Mop up any pooled water promptly.

If the area in question is an enclosed space that is not continuously exposed to outdoor conditions, TIER™ flooring is suitable. Avoid exposing your TIER™ floor to vastly different conditions as this may result in accelerated differential weathering.

Yes, as long as the design and installation of underfloor heating is done by a competent professional to ensure no impact on the stability or level (Grade 1, SANS 10155) of the subfloor occurs.

The foamed IXPE underlay of TIER™ flooring provides great thermal insulation and is suitable with underfloor heating.
